写文件和二进制文件的读取

建新文件
file=open(“jh.txt”,“a”) #建新文件

建新文件夹
os.mkdir(“wenjian”)

普通文件内容写入
with open(“jh.txt”,“w”,encoding=“utf-8”)as f:
data = “太上台星，应变无停。驱邪缚魅，保命护身。\n智慧明净，心神安宁。三魂永久，魄无丧倾。”
f.write(data)
f.close()

结果

二进制文件输入
with open(“jh.txt”, “wb”) as f:
data = b’Too star, strain no stop.Drive away evil spirits and protect your life.\nWisdom is clear, and peace of mind.Three soul permanent, soul without loss.’

f.write(data)
f.close()

结果

1. 读取二进制文件

首先使用open函数打开文件，打开模式选择二进制读取"rb"。
f = open(jh.txt, “rb”)

#单继承
class Prentice(Master):
pass
#多继承
class Prentice(Master, School):
pass

#子类重写父类同名属性
class Master(object):

def __init__(self):
    self.kongfu = "古法配方"

class Prentice(Master):
def init(self):
self.kongfu = “猫氏配方”
